' A y I 7 A lication-filed ctober 12,"1926 I sei-ia1.-No.-141,19sQ Q I This invent-ion relates to gate valves-and y it IS fiIlObj'GCi) of the invention to provide-a deviceof this kind for use in 1 connection with a laundry tub, washer or the like where rapidemptymgis required. w:

'It is also an object of thelnventioneto provide in a device, of this kind means to take up Wearon the valve proper together \Vltll means to assure tight and effective seatlng of theevalve proper ;w1thout am ming.

l .The invention consists in the details of construction and in the combinationand arrangement of the-several parts-of my im proved gate valve whereby certain ime tantadvantages are attained and the device rendered simpler, less: expensive and otherwise I more convenient and advantageous-for use, r as i will "be hereinafter more fully set f0rtl1.- vij'rr j f y It p 7 The novel features of invention will hereinafter befdefinitely claimed. 1

--In:;-order that my invention may. bethe" better :nnderstood, I;wil1"-now proceed to describe the, same with reference tov the accompanying drawing, wherein Figure 1 is ta view in topplan illustrating agate valve constructed in accordance witl an embodiment of my invention; &

Figure. 2 is a sectional view -taken*sub-i stantially on the line 2-2 of Figure :1;

Figure 3 tie 'a sectional view taken substan tially on the lineB-S of Figure 2; 1

Figure 4 is a view partly in sectionand partly in elevation of a modified form of invention.

As disclosed in the accompanyingdrawing, F denotes a frame of requisite dimensions and which has disposed thereover a plate 2 held in applied posit-ion by the bolts or nuts 3. The plate 2.is provided with an aperture 4 which is adapted to be positioned directly under anopening in a'tank, laundry tub, washer or the like from which rapidemptying is desired.

Opposed members 5 of the frame F are provided 'therealong with the depending flanges 6, similar endsof which having their lower portions extended; to provide bearing arms 7 for an operating shaft 8. One end portion of this; shaftiS, as herein disclosed,

has fixed thereto a hand lever 9 whereby requisite rocking movement may be imparted to the shaft 8 when desired. The shaft 8 substantially midway of the bearing arms 7 has fixed thereto an upwardly disposed reels.

I MEaCh f-the flanges 6 is provided 1111110, theupper orouter end portion of whiclr'is operatively connected, as 'at'll, to a head 1 2'carried 'by the outer endporti on of awrod 14.1 1 I The-rod' 1a is slidably' disposed through the centraljportionof a member 15 of the frame F and has its inner portion operatively connected as at- 16, with avalv'e member'l7.- The end edge faces of the valve member17 are provided with the grooves 18 which receive inwardly extended guide flanges or tongues 19 carried by the members 5 ofthe frameiF; The grooves 18 receive these flanges or tongues 19 with-sufli cient freedom to'allow the valve member 17 ;to move up for close contact with the-plate ltd close the opening 4. i

Each end portion of the valve member 17 is provided with a depending-flange-2O havwhereby said bar 22 is supported for adjust ment' movement in a verticaldirection an'd in substantially a fixed path of travel. ith the inwardly disposed-lugs 25 arranged below a bar 22 andthrough each] of which lugs is threadedfrom below a screw 26 having 001 tactw it-h the under face" of the bar 22.-1By

requisite adjustment of the screws 26 the bar 22 may be properly adjusted with respect to member 17 to move toward theplate 2 and thus assure a most effective closing action of the valv member 17. However, to prevent jamming of the valve member 17 I provide the screws 27 each of which is threaded through the outer member 15 of the frame F and in the same plane with the valve mem-' ber 17. These screws 27 provide adjustable stops with which the valve member 17 earn tacts when moved into its closed position; H

In the embedunem; arm invention as ill lnstratcd in Figure 4, the valve member 17 is provided at one end portion with depending flanges 28 between which extends anend portion of a rock arm 29 carried by the shaft 30. The portion of the arm 29 extending be tween the flanges 28 carries a roller 31. Upon rocking of the shaft 30, by the lever 32 or the like, the requisite sliding movement will be in'iparted to the valve member 17.

From the foregoing description it is thought to be obvious that a gate valve constructed in accordance with my invention is particularly well adapted for use by reason of the Convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptihle of some change and modification without departing from the princi les and spirit thereof and for this reason I to not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in pactice except as hereinafter claimed;

I claim 1. A. valve structure comprising a plate having a discharge opening, a frame associated with said plate, a slide valve slidably suj'iported by the plate. for movement across the opening, said slide valve also having bodily moven'ient toward or from the plate,- flanges depending from the slide valve and having their lower edges inclined, bars, said bars having edges inclined similar to the inclined edges of the flangesbf the slide valve, and means on the frame for supports ing the bars in such position whereby the inclined edges of the flanges of the slide valve engage the inclined edges of the bars when the valve is moved into closed position to force the valve toward the plate, the means for supporting the bars being adjustable to regulate the Josition of the bars relative to the plate, an means carried by the bars and co-operating with the frame for guiding the adjusting movement of the bars.

2..A valve structure comprising a plate having a discharge opening, a frame associated with said plate, a slide valve slidably s 'ipported by the plate for movement across the opening, said slide valve also having bodily movement toward or from the plate, flanges depending from the slide valve and having their lower edges inclined, bars, said bars having edges inclined similar to the inclined edges of the flanges of the slide valve, means on the frame for supporting the bars in such position whereby the inclined edges of the flanges of the slide valve engage the inclined edges of the bars when the valve is moved into closed position to force the valve toward the plate, the means for supporting the bars being adjustable to regulate the aosition of the bars relative to the plate, sait frame adjacent: to the bars be-,

ing provided with slots, and members carried by the bars and extending within the slots to guide the adjusting movementof the bars.

3. A valve structure comprising a plate having a discharge opening, aframe associated with said plate, a slide valve slidably supported by the plate for movement across the opening, said slide valve also having bodily movement toward or froin the plate, flanges depending from the slide valve and having their lower edges inclined, bars, said bars having edges inclined similar to the inelined edges of the flanges of the slide valve, lugs carried by the frame and underlying the bars,- and members threaded through the lugs and engaging the bars from below, said members supporting the bars and adjustment of said members regulating the posi tion of the bars relative to the plate;

In testimony whereof I hereunto affix my signature;
